Description

Technical Field

[0001] This utility model relates to the field of rainfall monitoring technology, specifically to a rainfall monitoring instrument installation structure. Background Technology

[0002] A rain gauge is an instrument used by meteorologists and hydrologists to measure the amount of precipitation in a region over a period of time. There are many types of rain gauges, the most common being siphon rain gauges, weighing rain gauges, and tipping bucket rain gauges. A weighing rain gauge uses a container to collect rainwater and a weighing device to calculate the weight of the rainwater collected over a certain period of time, which is then converted to obtain the amount of precipitation.

[0003] To prevent wind from exerting force on the side wall of the weighing rain gauge's collection tube, thus offsetting part of the rainwater's weight and causing abnormal measurement results from the weighing sensor, utility model CN220855233U discloses a windproof weighing rain gauge (hereinafter referred to as Prior Art 1), which includes a horizontal base. A base is fixedly connected to the upper surface of the horizontal base, and a weighing sensor is fixedly connected to the upper surface of the base. A tray is fixedly connected to the top of the weighing sensor, and spring telescopic rods are fixedly connected to both sides of the tray. A collection tube is fixedly connected to the top of the spring telescopic rods, and a protective sleeve is fitted around the outside of the collection tube. The bottom of the protective sleeve is in contact with the upper surface of the horizontal base.

[0004] In the prior art 1, the wind force is used to avoid affecting the measurement accuracy of the symmetrical weighing rain gauge by setting a protective cylinder; however, in actual use, impurities carried by rainwater (such as leaves, dust, insects, etc.) will enter the water collection tank along with the rainwater. Excessive accumulation of impurities in the water collection tank will also affect the measurement accuracy of the symmetrical weighing rain gauge. Utility Model Content

[0005] The purpose of this utility model is to provide a rain gauge installation structure that, in practical use, can solve the problem in the prior art that impurities carried in rainwater will enter the water collection tank along with the rainwater, and that excessive accumulation of impurities in the water collection tank will affect the measurement accuracy of the weighing rain gauge.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A rainfall monitoring instrument mounting structure includes a support frame and a filter bucket, wherein the filter bucket is mounted on the support frame;

[0008] The filter bucket is provided with a liquid guiding slope and a filter screen is installed inside the filter bucket; a liquid guiding pipe is fixedly connected to the bottom end of the filter bucket and the liquid guiding pipe is used to slide to the liquid inlet end of the liquid collecting cylinder.

[0009] The liquid collecting cylinder is placed on a weighing mechanism, which is used to detect the weight of the liquid inside the collecting cylinder.

[0010] Preferably, the filter screen is detachably connected to the filter bucket.

[0011] Preferably, a pull rod is fixedly connected to the filter screen.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] See Figures 1-3 This embodiment discloses a rain gauge installation structure, including a support frame 101 and a filter 102, wherein the filter 102 is installed on the support frame 101;

[0034] The filter hopper 102 is provided with a liquid guiding slope 103, and a filter screen 104 is installed inside the filter hopper 102; a liquid guiding pipe 106 is fixedly connected to the bottom end of the filter hopper 102, and the liquid guiding pipe 106 is used to slide with the liquid inlet end of the liquid collecting cylinder 110.

[0035] The liquid collection cylinder 110 is placed on the weighing mechanism 107, which is used to detect the weight of the liquid in the liquid collection cylinder 110.

[0036] In this embodiment, both the support frame 101 and the weighing mechanism 107 are mounted on the base plate. The weighing mechanism 107 is a conventional spring weighing mechanism 107 that measures weight by the deformation of a spring, as is common in the prior art. Its structure and function will not be described in detail here. The filter hopper 102 mounted on the top of the support frame 101 can filter impurities carried in the rainwater. The support frame 101 supports the filter hopper 102, ensuring that the mass of impurities in the filter hopper 102 after filtration does not affect the mass of the rainwater in the collection cylinder 110. This ensures that the weighing mechanism 107 can accurately measure the mass of the rainwater in the collection cylinder 110. After the filtered rainwater enters the collection cylinder 110, it is placed... The weight of the liquid collection cylinder 110 on the weighing mechanism 107 increases and it moves downward. The weight of the rainwater in the liquid collection cylinder 110 can be calculated by the amount of movement of the liquid collection cylinder 110. By setting the liquid guide pipe 106, the liquid filtered by the filter bucket 102 can be guided into the liquid collection cylinder 110, preventing the liquid in the liquid collection cylinder 110 or the filter bucket 102 from overflowing from the gap between the liquid collection cylinder 110 and the filter bucket 102. Furthermore, by extending the bottom end of the liquid guide pipe 106 into the liquid collection cylinder 110, it can be prevented that if the liquid collection cylinder 110 separates from the filter bucket 102 due to excessive displacement during movement, the liquid in the filter bucket 102 or the liquid collection cylinder 110 will flow out or splash from the gap between the filter bucket 102 and the liquid collection cylinder 110.

[0037] In some embodiments, the filter screen 104 is detachably connected to the filter bucket 102. In this embodiment, the filter bucket 102 is provided with a first threaded groove, and the side of the filter screen 104 is provided with a first thread for engaging with the first threaded groove; when the filter screen 104 needs to be cleaned, rotating the filter screen 104 will separate the filter screen 104 from the filter bucket 102.

[0038] In some embodiments, a pull rod 108 is fixedly connected to the filter screen 104. The pull rod 108 facilitates the rotation and removal of the filter screen 104.

[0039] In some embodiments, a cover is threadedly connected to the pull rod 108. In this embodiment, a second threaded groove is provided inside the cover, and a second thread for engaging with the second threaded groove is provided at the end of the pull rod 108 away from the filter screen 104; the cover is a semi-circular cover with an opening facing downwards, and a guide arc surface is provided on the cover; during the collection of rain and snow, rain and snow falling on the guide arc surface can move under the guidance of the guide arc surface and fall into the filter hopper 102; when it is necessary to remove the filter screen 104 to clean the impurities remaining on the filter screen 104, the cover is rotated so that the cover moves downwards to contact the filter screen 104, and the impurities remaining on the filter screen 104 are then located between the cover and the filter screen 104. After the filter screen 104 is removed from the filter hopper 102 along with the pull rod 108, the cover and filter screen 104 are taken out together. This prevents impurities on the filter screen 104 from falling into the collection cylinder 110 through the gap between the filter screen 104 and the filter hopper 102 during the process of lifting the filter screen 104 out of the filter hopper 102, thus avoiding contamination of the collection cylinder 110 and affecting the measurement accuracy. In actual use, the length of the pull rod 108 can be selected according to the specific needs. This embodiment only provides one possible implementation and schematic drawings. Various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of this utility model. In some embodiments, the rotation directions of the first thread and the second thread are opposite. By making the rotation directions of the first thread and the second thread opposite, it is possible to avoid affecting the stability of the connection between the filter screen 104 and the filter hopper 102 during the process of rotating the cover to move the cover towards the filter screen 104.

[0040] In some embodiments, the support frame 101 is provided with a first stepped groove 111. In this embodiment, there are several first stepped grooves 111, which are connected and whose diameters decrease from top to bottom. By providing the first stepped grooves 111, filter hoppers 102 of different sizes can be supported and limited. In some embodiments, the weighing mechanism 107 is provided with a second stepped groove. In this embodiment, there are several second stepped grooves, which are connected and whose diameters decrease from top to bottom. By providing the second stepped grooves, liquid collecting cylinders 110 of different sizes can be supported and limited.

[0041] In some embodiments, a first heating plate 112 is installed inside the filter hopper 102. The first heating plate 112 is used to heat the rain and snow in the filter hopper 102 in a solid or solid-liquid mixed state, so that the rain and snow entering the filter hopper 102 will not remain inside the filter hopper 102 and affect the accuracy of the measurement, nor will it freeze at the filter screen 104 and obstruct the drainage.

[0042] In some embodiments, a second heating plate 109 is installed inside the liquid collecting cylinder 110. The second heating plate 109 is used to keep the liquid inside the liquid collecting cylinder 110 warm, so as to prevent the liquid inside the liquid collecting cylinder 110 from freezing during storage and causing deviation in the measurement results.

[0043] In some embodiments, a heat insulation sleeve 105 is installed on the pull rod 108. The heat insulation sleeve 105 is made of heat-insulating rubber material. By setting the heat insulation sleeve 105, the user can avoid being burned by the residual heat on the filter 104 when taking it out through the pull rod 108.

[0044] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
